Gecko Adhesives Moving from Robot Feet to Your Walls
Few robots are as elegantly designed as Stickybot, Stanford's original robotic gecko. The bio-inspiration extends all the way down to the toes, which featured an early generation of gecko toe adhesive. Geckos stick to things using van der Waals' forces generated between the tiny fibers on their toes and whatever surface they're on: it's not sticky in the same sense that glue or tape is sticky; it's a molecular attraction that works on the smoothest of surfaces and can be used over and over. It sounds like something that might be useful apart from robots, and it looks like artificial gecko toes are about to go mainstream, with super strong, reusable Geckskin.
